CORNER-JOINT FOR CAR-FRAMES AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed February 13, 1906. Serial No. 300.857.

tion, reference being had to the accompany ing drawings, of which Figure 1 is a plan view of a corner of a carframe, showing my invention applied thereto. Fig. 2 is an end view of -Fig. 1 looking toward the brace-piece. Fig. 3 is a section on line as as, Fig. 1.

The object of this invention is to provide a strong and efficient corner-joint support or brace for frames of cars, car-trucks, automobiles, or other frames that are subjected to great strains, and which corner-j oint support canbe readily applied.

To this end the invention, broadly con sidered, comprises a metal box adapted to incase the adjacent ends of the corner-pieces of a car or similar frame from which projects a stem or shank that passes through an opening in a brace-piece within the corner, which brace-piece extends between the cornerpieces at a distance from the corner-joint and is secured thereto, the said stem or shank being clamped to said brace-piece by a nut or the like on the screw-threaded free end of said shank or stem. p

In the drawings, 1 1 are two of the usual wooden pieces forming the frame of a car, car-truck, or the like and which meet to form a corner. The ends of these pieces 1 are inserted in and entirely incased by sockets 2 of a box 3. Projecting inwardly from the box 3 is a stem or shank 4, whose free end is screw-threaded and passes through a hole 5, through a brace-piece 6 of suitable metal. Said brace-piece 6 extends between the frame-piece 1 1 a suitable distance from the corner and by means of bolts 7 is secured thereto. the brace-piece 6 by a nut 8, screwed on to said shank and bearing against the outer side of the brace-piece.

The stem or shank 4 is secured to When my invention is applied to a corner ofa car-truck or automobile frame, it will be observed that the adjacent corner-forming ends of the wooden frame-pieces are entirely incased within the sockets of the box 3,

thereby not permitting movement in any di.

rection of the said ends of these pieces. Also the brace-piece 6 being secured to the pieces 1 at some distance from the corner prevents any tendency to vertical movement of the wooden pieces 1. Thus the whole structure forms a very strong and efiicient cornerjoint. Also if there should be any tendency of the adjacent corner-forming ends of the pieces 1 to spread, by tightening the nut 8 the same may be prevented.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A corner-joint support for car-frames and the like, comprising the combination of the box, entirely encasing the adjacent cortending inwardly from said box and whose free end passes through an opening in said brace, and is screw-threaded on its said free end, and the nut on said free end, clamping said stem to said brace-piece, substantially as 'set forth.

In testimony whereof I have hereunto af fixed my signature.

FRANK BEVAN.
